The Dutch company Ecofuels produces biogas from vegetable-based material. Pentair Haffmans was awarded a contract for the supply of a biogas upgrading system, that will enable the company to generate more than 2,200,000 m3 of biomethane per year and recover 2,520 tons of food-grade carbon dioxide (CO2).
Ecofuels is an initiative of the Dutch companies Laarakker Groenteverwerking B.V. and Delta Milieu Compost & Biomassa. Laarakker grows 110,000 tons of vegetables annually on 3,500 hectares (8,650 acres) and sells them to producers of canned, frozen and juice products. Delta Milieu Compost & Biomassa is a vegetable waste management specialist that processes 400,000 tons of vegetable waste to compost each year, which is sold as fertilizer to agricultural and gardening enterprises.
